Derek Holzer
Derek Holzer (USA 1972) has performed live audiovisual sets using laptops and the Pure Data programming language for several years. During this time, he became frustrated with the performance limitations of the computer and began separate experiments with all-analog systems. These experiments came together during a workshop on art for the overhead projector at the Moltkerei in Cologne in August 2007. Inspired by some of the pioneering 20th Century electronic music instruments such as the ANS Synthesizer, the Variophone and the Oramics system (see HISTORY page on website), Holzer developed electronic and graphical systems for playing light on the overhead projector.
